To all 'whom it may concern:

Be it known that l, JonN WALTER (ilsmai., a citizen of the United States, residing at Baltimore city and State of Maryland, have invented a certain new and useful Cable-Stripping Machine, of which the iollowing is' a specification, reference being had thereinl to the accompanying drawing.

This invention relates to cable stri ping machines, the object of the invention eing to provide a machine for cuttin and disintegratin underground and over lead cables and faci itating the recovery of the lead casings and copper strand. fillings of the cables in an ex editions and ractical manner.

A furt 1er object of t 1e invention is to pro-y vide in connection with oppositely arranged cutters for severing the outer casing of the cables, means for varying or adjusting the relative distance between the cutters in order to accommodate cables of different sizes.

A further object of the invention is to provide cutters which are yielding and selfadjusting in order to accommodate inequalities'or undulations.

A still further object of the invention is to provide means for feeding the cables through the main throat of the machine and for varying or adjusting the distance between the feed rolls to accommodate cables of dilt'erent sizes.

A further object of the invention is to provide in connection with the cutter driving shafts, means for varying or adjusting the distance between said shafts; also means for permitting the cutters carried by said shafts to shift lengthwise of the shafts without effecting their operative relation te' the other parts of the machine.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the inventlon consists in the novel construction, combination' and arran ement of parts as herein fully described, il ustrated 'and claimed.

In theV accompanying drawin s:-1"igure 1 is' a side elevation of a ca le stripping machine embodying the present invention. Fig. 2 is a central vertical transverse section thereof on the line 2-2 of Fiv. 1. Fig. 3 is a horizontall section through he machine on the line 3--3 oi Fig; 1. Fi 4 is a detail horizontal section t rough the central portion of the machine taken on the line 4-4 of 5 is a' detail elevation of thev feedr I0 .I

The machine comprises a suitable frame embodying a horizontal su port or base 1 which is sustained at a suita le elevation by means of supporting legs 2 while extending upward from the base is a lurality of standards 3 arranged in pal'alel pairs, as best shown in Figs. 1 and 3, said standards being tied togetherat their upper ends by means 'of cap pieces or tie bars 4 held in place by bolts or screws 5 or their equivalent.

Arranged just above the base 2 are parallel 'shafts 6 and 7, 6 designating the lower feed roll shaft which carries the positively driven' feed roll 8 providedV with cable engaging teeth 9, while the shaft 7 has mounted thereon the lower cutter 1t). The shafts 6 and 7 are mounted in stationary bearing boxes just above the base 1 and between the pairs of parallel standards 3, said boxes being similar to those shown in Figs. 1 and 3 but arranged beneath the boxes shown in said.

figures. Above the shaft 6 is arranged the upper feed roll shaft 11 which is journaled in bearing boxes 12 movable up and downybetween the parallel 'standards 3, veach of said boxes being provided at opposite sides with ,guide lianges 13 which bear against opposite sides of the standards 12 as best shown in Fivx 3. The shaft 11 carries the upper feed toil 14 which is an idler or a driven roll.

other words, the u Y per feed roll 14 does not need to be ositive y driven but it will suffice for said roi. to be driven by contact with the cable in its passage through the mchhe Both the lower feed roll 9 and the u )per feed roll 14 are provided with concave( peripheries as shown in Fig. 5, and the lower ositive feed roll has the teeth 9 projecting rom such concaved eriphcry so as to engage the under side of t e cable and force t e same onward through the machine. The upper feed' roll 14 is rendered adjustable toward and away from the lower iced rollin order to accommodate cables of different sizes by makin the bearings adjustable up and down Eetween the standards 18 which is aocomplished by means of a pair of adjusting screws 15 having a keyed or shouldered engagement at their lower ends with the boxes 12 and having a threaded engagement where they pass through the cap pieces' 4 of the frame. Each of said screws is rovided at its upper end with a hand whee 16 for adjusting it and may also be locked by means of a jam nut 17 which may be turned up tightly against the cap picots ,4r

Arranged above the shaft 7 is the upper l bearings 39 having dove-tailed portions or cutter shaft 18 the saine being journaled in boxes 19 arranged between the parallel standards 3 et the opposite side of the center of the machine which boxes correspond with the sliding boxes 12 above described and are rendered adjustable in the same manner by means of adjusting screws 2U having-the same relation to the trame of the lmaehine.

This provides for adjusting the. upper rota-ry' cutter 21 upward and ,lownward or in other words toward and away from the cutter 1|). 'lhe cutter 1U is carried by a sleeve 22 fast on the lower cutter shaft 7 while the. upper eutter 21 is carried by a sleeve 23 fasten the upper cutter shalt 18 both'ol' which shafts are positively driven by the gearing herexnalter described.

In addition to the upper und lower rotary cutters 21 and 10, oppositely arranged side cutters 24 and 25 are provided whieh are carried by sleeves 2G and 27, respectively, the same heilig shiitable lengthwise of o. pair of opoositely arranged shafts 28 and 2) extending about vertically und loeatedwithin the planes ol' the standards 3 as shown in Fig. L. Furthermore each ol' the sleeves 26 and 27, while adapted to slide on its res ee.-

tive shaft or :."J is keyed to said sha .t as

shown :it so that eat-h of the side. entiers is driven by its respective shalt. The side cutters 24 und .25 are rendered adjustable up and down by means ol' a yoke or double fork 3l in the form ol' n plate disposed horizontnllyand having fork ends 32 which are received in the. grooves 33 et' rollars 34 on the upper ends ol the sleeves 2G and 27, the yoke being adjusted up and down by menus of a yoke adjusting,r screw 35 having a keyed engagement at its lower end with the yoke und threaded through the top l on the l'rame where it may he held lixed by means oil' a, iam nut adupted toturn up tightlyagainst i the frame.4 'l'lu` screw fris further Provided :it its upper end with u hand wheel 3S to lneilitate the adjustnu-nt .-l' the screw. ln nddition to the up and down adjustment ol' the yoke 3l, said yoke is adapted to oseillute upon its center relatively to the. point where it is eonneeted to the lont-r end olv the adjusting serew 35, the eonneetlon between the adjusting seri-w l?) and the yoke IH being of sui-li :i loose nature as to admit ol' a limited oseiilatory movrnnot ol'seid yoke, this being for the purpose ol' permitting` the side eutl l l The shal'ts 2S and .fl ari' llnirnaled :tttheir upper ends in horizonlall \y shii'table slide tlanges 4 which are received in n dove-tailed guide-wa] or groove. 41 in the upper part e. the frame, the bearings 3!) being held towzmi' each other by oppositeljf arranged set serons 42 threaded through lugs or hrnekets 13mm the upper part of the frame und adapted :o he fixed by means ol jam nuts tl.
